IMPROVEMENT IN MECHANICAL MOVEMENTS.

' Specification forming part of Letters Patent No. 118,016, dated August15,1871.

To all 'whomV it may concern:

Be it known that I, CHARLES W. HURD, of Gomstocks Landing. in the countyof lashington and State of New York, have invented a new and usefulImprovement in Mechanical Movement; and l do hereby declare that thefollowing is a full, clear, and exact description thereof, whichwillenable others skilled in the art to make and use the same, referencebeing had to the accompanying drawing forming part of thisspecification, in which- Figure 1 is a topview of my improved movement.Fig. 2 is a side View of the same. Fig.

3 is a detail view of a modified form ofthe handlever.

Similar letters ofreference indicate corresponding parts.

My invention has for its object to furnish an improved mechanicalmovement for workin g churns, clothes-washers, wool-washers,iulling-machines, clipping-machines, reapers, straw-cutters,sawing-machines, Src., and which shall be simple in construction andeifective in operation; and it consists in the construction andcombination of the various parts of the movement, as hereinafter morefully described.

A represents the longitudinal bars ofthe frame, which are connected bycross-bars B, and supported by legs C of suitable length. D are levers,four, more or less, in number, which are pivoted to a bar or shaft, E,attached to the frame A B, and which are kept in proper relative posi- 1tion by washers placed upon the rod E,between the said levers D. F is ahand-lever, which is pivoted at its central point to the end of thecentral bar A, or to some other suitable support. To the lever F, atequal distances from its central or pivoting point, are attached twocrossbars, G. To the upper ends of the cross-bars G are pivoted theouter ends of the upper connecting-rods H, the inner ends of which arepivoted to the upper ends of the first and third levers D. To the lowerends of the cross-bars G are pivoted the outer ends of the lowerconnecting-rods H, the inner ends of which are pivoted to the second andfourth levers D, as far below the shaft E as the other rods H are aboveit. A By this construction, by working the lever F, which may be done byhand-power or by any other convenient power, the levers D will beoscillated. If desired, the lever F may be pivoted to a standard betweenthe two inner levers D, and may be connectedwith the ends of said leversD by staples j", or other equivalent means. This arrangement can beemployed when only one or two levers D are to be used. To the upper endsofthe levers D may be attached, or upon them may be formed, weights I,to increase the working effect of said levers D. J are rubber ormetallic springs, secured to the frame-work of the movement in such aposition that the upper ends of the levers D may strike against them andreceive an impulse from the elasticity of the.

said springs. With the lower ends of the pivoted levers D may beconnected the dashers of a churn, the rubbers of a washer, a saw orsaws, cutters, or any other tool, which does its work by a reciprocatingmovement.

By this movement one or more of the levers D may be used, as the work tobe done or the power to be applied may render necessary. By thisarrangement, also, should any one of the levers or rods fail, it willnot affect the operation of the other parts, each of the levers Dworking independently of the others.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. An improved mechanical movenfent, formed by thecombination of the horizontally-vibratin g driving-lever F andvertically-vibrating levers D, four, more or less, with each other,substantially as herein vshown and described, and for the purposes setforth.

2. The combination ofthe weightsl and springs J either or both, with thelevers D and F, substantially as herein shown and described, and for thepurpose set forth.
